Cl. F16h1/06, 57/00 US. Cl. 74-4103 Claims ABSTRACT OF THE DISCLOSURE A device for the actuation of amangle wheel by a pinion. The latter is disposed in a housing which issupported at a fixed point and is guided by a plurality of trains whichselectively can engage the guiding elements of the housing from theoutside, the inside or from both the outside and inside.

The invention relates to a device for the actuation of a mangle or ringgear by a pinion disposed in a pinion housing which is supported at afixed point and guided by appropriate elements on tracks concentricalwith the mangle wheel. 1

In known devices for the transmission of motion of a ring gear or manglewheel of large diameter or of a tilting gear for a steel mill converter,thepinion housing is supported by smooth tracks, concentrical to thegear axis, by means of rollers disposed on the-housing A known devicefor the balancing of changes in meshing of gear drives also used smoothtracks with a mangle wheel. Therein, one of the bars carrying: the driveelements serves as guideway. However, it usually is necessary to provideroller supports for the pinion housing on the side facing away from thepinion to, counteract the tendency of the pinion to jump out of the ringgear. This requires additional guideways which frequently are difficultto place, for instance when the ring gear isdisposed on a drum.

It is the object of the invention to provide for mangle wheels guidewaysor trains which selectively can engage the guide elements of the pinionhousing from the inside or the outside, or from both the inside andoutside.

The device according to the inventon provides a drive for a mangle wheelby a pinion mounted in a pinion housing. The latter is supported at afixed point and is guided by suitable directional elements along trackswhich are concentric with the wheel. The free ends of the meshing pinteeth form the tracks. The pinion housing may be a cradle or slidingcarriage. Such a construction wherein friction occurs between thehousing and the ends of the pin teeth can be chosen when the guidance ofthe pinion housing is in effect only intermittently, i.e., when theposition of the pinion axis relative to the axis of the ring gear hasbeen fixed by other means.

In a preferred embodiment of the invention, the ends of the pin teethcarry rollers which form roller trains, and the directing elements areguides which are fastened to the pinion housing in an articulatedmanner.

The number and disposition of the guides depends upon the generalprovisions; they may engage the roller train on the side facing awayfrom the pinion or else may be provided on both sides of the rollertrain.

Good direction of the pinion housing can be effected when per rollertrain, i.e., on both sides of the ring gear, on the track facing awayfrom the pinion, two guides are provided and one guide is disposed onthe track facing the pinion.

The invention now will be more fully explained with reference to theaccompanying drawings.

In the drawings:

FIG. 1 is a plan view, partly in section, that schematically shows aring gear on which a pinion housing, provided with guides, is supported;

FIG. 2 is a side elevational view thereof; and

FIG. 3 is a plan vview similar to FIG. 1, showing a modifiedembodiment'having three pairs of guides.

Referring now to these drawings, a driving pinion 1 is installed inpinion housing 2. The latter has guides 3 fastened to it in anarticulated manner. Guides 3 are'disposed swingably about bolts 4.Pinion housing 2 is connected to a fixed point by a support 5.

The gear teeth of pinion 1 engage in pin teeth 6 of a mangle wheel oflarge diameter. The free ends of the pin teeth 6 carry rollers 7 thatform a guideway, such as two roller trains, namely one train facing awayfrom, and one facing, the pinion 1. FIG. 2 shows the bars 11, supportingthe teeth 6.

Pinion 1 is actuated by shaft 10 by way of a reduction gearing composedof gears 8 and 9.

In the embodiment according to FIG. 3, the roller train on the sidefacing away from pinion 1 is assigned two guides 3 and that facingpinion 1 one guide 3a. The latter is disposed swingably about bolt 4a.This provides an exactly defined engagement of pinion 1 in the meshingteeth or leaves.

It is a considerable advantage of the invention that a concentricguideway is provided by the mangle wheel and the use of the pin teeth 6carrying extensions in the form of rollers 7. Upon suitable dispositionand formation of the guides, the construction according to the inventionis applicable to ring gears which are out of round because the rollertrain forcedly follows each curvature in the graduated circle. Thus, theinvention facilitates the manufacture of drives for ring gears of largediameter by simple means with the aid of the mangle wheel.

We claim as our invention:

1. A device for the actuation of a mangle wheel having pin teeth whichcomprises a pinion engaging the teeth of said mangle wheel; a housingfor said pinion in which said pinion is journall'ed; said housing beingpivotably supported at a fixed point; guide elements mounted withrelation to said housing; and extensions formed on said pin teeth andconstituting a guideway, said guide elements engaging said guideway forpositioning said housing rela-. tive to said pin teeth.

2. The device as defined in claim 1, wherein said extensions areprovided with rollers forming trains; and said guide elements are guidesdisposed on said housing in an articulated manner.

3. The device as defined in claim 2, wherein, on the roller train facingaway from the pinion, two articulated guides are assigned and, on theroller train facing the pinion, one articulated guide.
